| BOE Publication | November 2, 2026 |
| Entry into force | November 2, 2026 |
| Developer | BRUC Las Quinientas, SL |
| Location | Puerto Real and Jerez de la Frontera (Cádiz) |
| Total approved capacity | 33 MW (5 wind turbines × 6.6 MW) |

| BOE Reference | BOE-A-2026-22987 |
The «Las Quinientas» wind farm receives environmental approval to hybridize with the already operational photovoltaic plant of the same name in the province of Cádiz. The resolution, published on November 2, 2026 with reference BOE-A-2026-22987, represents the essential prior step for BRUC Las Quinientas, SL to begin construction of the wind module.
The approval comes after a project reconfiguration process that reduced the number of planned wind turbines by half, from 11 to 5 machines, with the aim of minimizing impact on birds and protected natural areas in the region.
What does this regulation establish?
The Directorate General for Quality and Environmental Assessment issues a conditional favorable environmental impact declaration for the project. This means that the developer can proceed toward administrative authorization, but must comply with a set of mandatory environmental conditions.
The approved technical elements are as follows:
| Element | Detail |
|---|---|
| Number of wind turbines | 5 units |
| Unit capacity | 6.6 MW per wind turbine |
| Total capacity of wind module | 33 MW |
| Hybridization | With the «Las Quinientas» photovoltaic park already in operation |
| Evacuation infrastructure | Underground line at 30 kV |
| Line length | 23.5 km |
| Destination substation | Cartuja II |
| Selected alternative | Alternative 1 (the furthest from protected natural areas and Ramsar wetlands) |
| Affected municipalities | Puerto Real and Jerez de la Frontera (Cádiz) |
The selection of Alternative 1 was decisive: it presents the greatest distance from protected natural areas and Ramsar wetlands in the surrounding Cádiz region, which justifies the environmental viability of the project compared to other discarded configurations.
The mandatory environmental conditions are structured in two phases:
- Construction phase: measures to minimize impact on fauna, especially birds, and surrounding habitats.
- Operation phase: continuous monitoring of impact on avifauna and implementation of wind turbine shutdown protocols if risks to protected species are detected.
Economic and operational impact
For BRUC Las Quinientas, SL, the favorable DIA is the unlock for an investment that had been in reconfiguration process since the initial proposal of 11 wind turbines. The reduction to 5 machines implies a significant adjustment in installed capacity, but also in construction costs and the environmental risk profile of the project.
From an operational perspective, wind-solar hybridization over the same evacuation infrastructure (30 kV line to Cartuja II) allows optimization of the grid connection already planned, reducing the marginal cost of wind evacuation by sharing infrastructure with the existing photovoltaic plant.
The environmental conditions of the DIA generate specific operational obligations that the developer must budget for:
- Surveillance and monitoring programs for avifauna during construction and operation.
- Possible technical shutdowns of wind turbines upon detection of protected species, with consequent impact on estimated production.
- Coordination with the administrations of the municipalities of Puerto Real and Jerez de la Frontera for the layout of the 23.5 km underground line.
Who does it affect?
- BRUC Las Quinientas, SL: direct developer of the project, primarily affected by DIA conditions and execution timelines.
- Municipality of Puerto Real (Cádiz): main location of the wind farm and part of the evacuation route.
- Municipality of Jerez de la Frontera (Cádiz): affected by the 23.5 km underground evacuation line route.
- Renewable energy developers and promoters with projects in areas with protected natural areas or Ramsar wetlands: this case is a reference on how the administration requires project reconfiguration to obtain a favorable DIA.
- Environmental advisors and engineering consultancies managing environmental impact assessments for wind farms in Andalusia.
- Operators of the Cartuja II substation and grid managers in the Cádiz area, who will receive evacuation from the new wind module.
Practical example
BRUC Las Quinientas, SL initially presented a project with 11 wind turbines. Following the environmental assessment process, the Directorate General for Quality and Environmental Assessment required successive reconfigurations to reduce impact on birds and protected areas. The result: the project was reduced to 5 wind turbines, which represents less than half the original capacity.
With the favorable DIA now published, BRUC Las Quinientas, SL can proceed toward administrative authorization of the project. The underground evacuation line of 23.5 km at 30 kV will connect the farm with the Cartuja II substation, sharing infrastructure with the already operational photovoltaic plant. This hybridization model —wind + solar over the same grid connection— is precisely what the administration is incentivizing to optimize the use of grid access points.
The case illustrates a clear trend: wind projects in sensitive areas of Andalusia must anticipate reconfiguration margins (reduction of units, change of route alternative) as part of the DIA obtaining process, which directly affects financial models and development timelines.
What should companies do now?
- BRUC Las Quinientas, SL: initiate administrative authorization procedures. The favorable DIA is a necessary but not sufficient condition. The developer must now process administrative authorization before the competent body of the Junta de Andalucía to begin construction.
- Incorporate environmental conditions into the executive project. The DIA conditions —especially those related to bird protection— must be transferred to the construction project and environmental monitoring plan before starting work.
- Coordinate with the town halls of Puerto Real and Jerez de la Frontera the layout of the 23.5 km underground line to obtain necessary municipal licenses and permits.
- Developers of other wind projects in sensitive areas: review the Las Quinientas case as a reference on the criteria of the Directorate General for Quality and Environmental Assessment for projects affecting protected natural areas and Ramsar wetlands in Andalusia.
- Advisors and consultancies: update environmental assessment models for wind projects in Cádiz and Andalusia incorporating the alternative selection criteria applied in this case (distance to protected areas as a determining factor).
Frequently asked questions
How many wind turbines does the Las Quinientas wind farm in Cádiz have approved?
The DIA approves 5 wind turbines of 6.6 MW each, with a total capacity of 33 MW. The original project contemplated 11 wind turbines, but was reduced by half following successive reconfigurations to minimize impact on birds and protected natural areas.
What is wind-solar hybridization in the Las Quinientas project?
Hybridization consists of integrating the new wind generation module (33 MW) with the «Las Quinientas» photovoltaic plant already in operation, sharing the same evacuation infrastructure: an underground line at 30 kV of 23.5 km that connects to the Cartuja II substation.
What obligations does the DIA impose on developer BRUC Las Quinientas, SL?
The environmental impact declaration establishes mandatory conditions in two phases: during construction (fauna and habitat protection measures) and during operation (continuous monitoring of impact on avifauna and wind turbine shutdown protocols in case of risk to protected species).
Why was Alternative 1 chosen for the wind farm route?
Alternative 1 was selected for being the furthest from protected natural areas and Ramsar wetlands present in the surroundings of Puerto Real and Jerez de la Frontera (Cádiz). This criterion of distance to sensitive areas was decisive for obtaining the favorable DIA.
When does the environmental impact declaration for the Las Quinientas wind farm enter into force?
The resolution was published in the BOE on November 2, 2026 (reference BOE-A-2026-22987) and entered into force on that same date. From that moment, the developer can initiate administrative authorization procedures for wind farm construction.
